Went web shopping for one of these straps and to my surprise found a whole lot at HN at pretty much 50% off http://www.harveynorman.com.au/catalogsearch/result/?q=Black… . The RS series are well reviewed on many photo sites but were too rich for me at their normal $100+ price. Only downside is that HN's half yearly clearance ends tomorrow.
This is what I bought - sticker price $109.95 reduced to $55.

Finally got my hands on the RS-Sport! Picked up the last one at Mandurah. (A bit far from home, but we were part way there thanks to kids' ice skating lessons, so…)
